OVEN-PLATE.

SPECIFICATION forming part of Letters Patent No. 487,911, dated December 13, 1892. Application filed March 29, 1892. Serial No. 426,863. (No model.)

To all whom it may concern:

Be it known that I, ISAAC BROOKE, a citizen of the United States, residing at Pottstown, county of Montgomery, and State of Pennsylvania, have invented a new and useful Improvement in Oven-Plates, which improvelnent is fully set forth in the following specification and accompanying drawings.

My invention consists of the novel construcro tion of an oven-plate of a stove or range, fvhereby the heating-surface of the same is increased.

It also consists in providing the plate with a flue or iiues for causing a circulation of hot air in the oven.

Figure 1 represents a face view of an ovenplate embodying myinvention. Fig. 2 represents a horizontal section on line a; Fig.

1. Fig. 3 represents a vertical section on line 2o y y. Fig. 4 represents a vertical section on line z z.

Similar letters of reference indicate corresponding parts in the several gures.

Referring to the drawings, A designates an z 5 oven-plate, the same being formed corrugated, as at B, whereby the heating-surface of the plate is vastly increased. To the walls of some of the corrugations are bolted or other- Wise secured the plates C, which form the 3o flues D, which are -open at top and bottom and formed with passages E near the top, whereby hot air in the oven may enter said dues and escape therefrom, thus re-entering the oven and thereby causinga circulation of the hot airin the oven. Atlue F is also formed by means of a plate G and lthe adjacent portion of the plate A., the same being open at bottom and closed at top. In the plate Aare openings H, which are in communication with the exit-Hue of the stove or range, so that some 4o of the air may escape from the oven, and thus cause a draft in the latter, whereby fresh air may be drawn into the same.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isl l. An oven-plate having a corrugated surface and plates secured to the inner face of the Walls of the corrugations, forming lues open at top and bottom, said plates having 5o openings therein, substantially as described.

2. An oven-plate having a corrugated surface, plates secured thereto on the inner face, forming iues open at top and bottom, and a plate secured to said oven-plate, forming a ue open at bottom and having an exit at top through an opening in the ovenplate, said parts being combined substantially as described.

ISAAC BROOKE.
